10 TLOEULA ADENENSIS. 



Salt spent several days ; and the fragment of S. Arabica mixed with the 

 former species is most likely from Aden. 



Had R. Brown seen flowering specimens of S. Arabica, he would doubt- 

 less at once have distinguished the two species, and, moreover, would have 

 united his S. Abyssinica with his other species S. Triphaca, described from 

 an imperfect specimen in fruit in the Paris Herbarium, collected by Lou- 

 reiro at Mozambique, and which seems to have been considered distinct 

 by Brown, on account of the fruit differing from what he mistook for the 

 fruit of S.. Abyssinica, but which I have above shown to be the fruit of S. 

 Arabica. 



Figure B. of Plate II. is taken from a Sterculia in the Hookerian 

 Herbarium, from near Mozambique, named S. ipomecefolia, Gerke, a careful 

 comparison of which with the original specimens of S. Abyssinica, R. Brown, 

 convinces me that it is certainly the same as that species. S. Arabica is 

 easily distinguished from S. Abyssinica by its short-petioled, rotund, 

 rarely acute, and perfectly glabrous leaves, very short, axillary, simple, 

 nearly glabrous racemes, and by the markedly different fruit, which is only 

 half the size of that of <S. Abyssinica. 



The leaves, petioles, and peduncles of S. Abyssinica, besides possessing 

 other and more important characters, are always more or less tomentose.
